Be it known that we, DAVID BARTHoLoMEw and DAVID C.. DmsMoRE, of Kirkville, in the county of Wapyg ello, and State of Iowa, h'avevinvented a new and 4useful Improvement in Churns;' and we do hereby declare that Y the following is a full, clear, and exact description of vthe same, reference lbeing had to the annexed drawings, i making part of this specification, in which- Y Y i i Figure 1 is a perspective view, and.'

Figure 2 is a simlalrwiew of the dasher.` The same lettersA are used in -both figures for the indication of the same parts. The following description will enable persons skilled in the art to construct and operate our improved hurn.` :A is a. frame, constructed to hold the barrel of the churn irmlyin position, said barrel being eountersunk in the bottom of the vframe, and enclosed on all-sides by the cross-pieces thereof, oneof the latter, A', being hinged to the post at one end, and secured at'the -other sans to permit the-convenient removal of the barrel.` I .B isrthe barrel, covered' by the head B', through which passes the shaft of the oscillatiugf-dasher, C. The short ig shaft C', in the bottom thereof, rests on a stop iuthe bottom of the barrel. The dasher is made with floats,

conforming to the sides ofthe barrel, and attached` to the arms of two spiders, as clearly shown in iig. 2. To' the end of the shaft projecting through the head B"is attacheda horizontal armD, with a. series. of holes, to receive adjustably the hooked end of a -connecting-rod, E, which communicates a. reciprocating oscillation to the arm and dashcr by the movement'o't` the crank on the shaft F. This shnftis driven bya pinion, G, on the end thereof, in'towhchmcshes the spur-'wheel H, driven bythe win-ch I. llhe'poportionA of these wheels vdetermines the rate, and the position of the point of attachment of thcconnecting-rod E and arm D, the extent of the oscilla-tioneof the arm and dasher. i l What we claim as our invention, and desire to secure by LettersPatent, isjfl The combination of the churn and the frame A, constructed with a removable brace, A', and the arm D, for

Vgiving a reciproca-ting lrevolution to the dasher, and so adjustably connected with the Pitman E andL drivingmechanism that the churn may he removed from the frame, substantially as set forth.

In testimony whereof, we have signed our names Vto this` specification in the presence of two subscribing witnesses.
